QUESTION #52 Vector Operations and Components
Let A, B, C be three points in xy-plane, whose position vector are given by sqrt3hati+hatj, hati+sqrt3hatj and ahati+(1-a)hatj respectively with respect to the origin O. If the distance of the point C from the line bisecting the angle between the vectors overlineOA and overlineOB is frac9sqrt2 then the sum of all the possible values of a is:

QUESTION #53 Components of Vectors
If the components of veca=alphahati+betahatj+gammahatk along and perpendicular to vecb=3hati+hatj-hatk respectively, are frac1611(3hati+hatj-hatk) and frac111(-4hati-5hatj-17hatk), then alpha^2+beta^2+gamma^2 is equal to:
